Camelbak have applied their innovation to a children&8217;s specific bottle that&8217;s great in school bags on the hill or in the car. Completely intuitive the spillproof Big Bite valve can only be removed through the underside of the cap eliminating a choking hazard & making it easier to clean. An integral push-button flips up the Big Bite valve for use & being only 400ml a full bottle will never be too heavy for little hands.
